Benefits of technology
[0005]Disclosed herein are methods, systems, and computer readable storage media that provide for reducing elevation error in tracking systems using environmental pressure anomaly compensation. The disclosed techniques reduce elevation resolution error by accounting for various sources of environmental pressure variations that negatively impact elevation resolution error including: local environmental fluctuations, wide area environmental fluctuations (e.g. weather related environmental pressure variations), or a combination thereof. In some embodiments, the disclosed techniques utilize terrain elevation data to provide an absolute elevation reference. These and other features will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings and claims.
Problems solved by technology
Environmental pressure variations may affect the ability of the system to resolve elevation if not compensated.

Abstract
A method for determining an environmental pressure change affecting a pressure sensor within a portable device to determine an elevation of the portable device is disclosed. The method involves estimating a location of the mobile device, estimating an atmospheric pressure associated with the mobile device at a server based on data indicative of atmospheric pressure received from the mobile device, and generating the elevation of the mobile device based on the atmospheric pressure associated with the mobile device and reference data indicative of an absolute elevation reference. The absolute elevation determined may be based on the estimated location of the mobile device and elevation data obtained from a reference map.
